VAPOR on. BURNER.

Application filedDecember 29, 1923. Serial No. 683,454.

I 0 all whom it may concern Be it known that I, JACOB BARTEL, a citizenof the United States, and a resident of Hillsboro, in the county ofMarion and State of Kansas, have invented certain new and usefulImprovements in Vapor Oil Burners, of which the following is aspecification.

My present invention relates generally to oil burners and moreparticularly to vapor oil burners of a simple inexpensive type whosechief disadvantage arises from the fact that at low flame the vaporburns red and smoky due to the control of the fuel oil supply and thediminution of necessary pressure at the burner opening when this oilsupply is retarded.

Burners of this type commonly employ elevated supply tanks for the fueloil and the pressure of the gravity feed of the oil is necessary at alltimes if the burner is to produce the-same white, smokeless flame at alltimes during operation. It is the primary object to produce such aresult, to provide for a more effective and efficient control withuniform results at both high and low flame and to bring about thedesired result without complicating the construction of the burner orincreasing the cost thereof.

In the accompanying drawing which illustrates my invention and forms apart of this specification,

Figure 1 is a side view with the valve controlling parts removed, and

Figure 2 is a vertical sectional view taken substantially on line 2-2 ofFigure 1 showing the entire burner.

Referring now to these figures my invention contemplates a burnerwherein generating and vapor rings 10 and 11 are disposed at rightangles to one another and intercon nect in communicating relation attheir upper central portions as at 12. These rings are of sufficientlydifferent size so that the lower portion of the inner or vapor ring 11passes through the generating ring 10.

The two rings 10 and 11 are disposed above a' starting pan 13 from thecenter of which a hollow upright 1 1 rises to the vapor ring 11 withwhich it communicates, the said vapor ring having a burner opening 15 inits median line and in line with the axis of the upright 14. The wall ofthis opening is tapered to coact with the upper needle valve 16 of avalve stem 17 depending axially through the upright 14 and having itslower portion depending through an internally threaded guide tube 18below the pan 13.- The lower enlarged portion of stem 16 has threads 19,cooperating with the internal threads of tube 18 so that rotation of'thestem, applied for instance to its lower end which projects exteriorlythrough a packing nut or gland 20, serves to elevate or lower the needlevalve 16 within the burner opening 15 and thus control the flame throughits control of the amount of vapor passing through the burner openingwithout affecting the pressure behind the vapor.

As before stated, burners of the type to which my invention relates,employ elevated oil supply tanks and in the present instance such a tank(not shown) is in communication with the lower laterally deflectedportion of the generating ring 10 through a supply pipe 21 and a hollowupright 22 which rises through the pan 18 and connects with the lowercentral portion of the generating ring, as particularly seen in F igure2.

The upright 22 thus cooperates with up right 14: in supporting the rings10 and 11 in properly spaced relation above the pan 13 so that quickstarting is assured upon the burning of oil within the pan. Propergeneration of vapor within the ring 10 in action is assured by a flamespreader 23 in the form of a plate swung by virtue of its aperture lug24: upon a hook 25 depending from the connected upper portions of therings 10 and 11.

For the convenient control of the needle valve 16, the lower end of itsstem 17 may be universally jointed, as by means of a coil springconnection 26, to one end of a control rod 27 whose opposite end has ahandle 28. Thus the control rod and handle may be turned to practicallyany angle to the valve stem so as to permit of convenient installationof the burner in various uses.

It is obvious that in action the gravity feed of the fuel oil ordistillate is controlled by the back pressure of the generated vapor andthat it creates a pressure on the vapor which is constant at all timesduring action so that uniform results are assured so far as a white,smokeless flame either high or low is concerned. By the construction andarrangement shown I am able to bring about this result withoutcomplicating the burner as a whole or adding to its cost.

I claim:

A. vapor oil burner including vapor and generating rings of hollow formdisposed at approximately right angles and connected in communicatingrelation at their upper central portions, a fuel oil supply including apipe and an upright connected to the lower laterally deflected portionof the generating ring, a starting pan through one side of which saidupright extends, a hollow upright rising centrally from said pan, saidvapor ring having its lower central portion connected in connnunicatingrelation to the upper end of the latter upright and having a burneropening opposite the axis of said upright, an internally threaded tubedepending below the pan from said central upright, a needle valve withinsaid burner opening having a stem depending through the said upright andsaid tube and provided with threads engaging the threads of the tube,and means engaging the lower end of said stern for rotating the same andadjusting the needle valve including a control rod having a handle atone end and a universally movable connection at its other end with thesaid valve stem.

JACOB BARTEL.
